Can you solve this 1 Across clue from The Independent’s cryptic crossword? Scroll down for an explanation.

Let’s break it down.
Behold = Lo (as in look! see).
Fracas = Commotion. However, we lose an ‘m’ because of the direction ‘millions leaving’ (read about how letters often represent words in cryptics). This leaves ‘comotion’.
Lo + Comotion = LOCOMOTION. This synonym for ‘moving’ is our ten-letter answer.
